3 Claims.

This invention relates to attachments for sewing machines andhas particular reference to an embroiderer or device for simulating hand em-.

broidered fancy work.

The principal object of the invention is to provide an attachment, adaptable to conventional types of sewing machines, designed to stitch embroidery thread, or yarn, onto fabric in any design.

Another object of the invention is in the provision of an attachment of this character capable of keeping the embroidery thread or yarn taut in order that the stitching operation is properly completed and in preventing the stitching needle from sewing to the sides of the yarn or thread to be stitched, as well as in preventing the appliqued material from buckling or becoming overlapped.

A further object of the invention is in the provision of an embroidering attachment capable of twisting yarn, or similar material to be sewed, to fabric in a manner that the finished result of simulated embroidery is neat and closely sewed.

Broadly the invention seeks to provide an embroidery attachment for sewing machines capable of properly preparing yarn, or the like, for a stitching operation.

With the foregoing objects as paramount, other and lesser objects will become manifest as the description proceeds, taken in connection with the accompanying drawing, wherein:

Figure 1 is a perspective View of the invention attached to the head of a sewing machine.

Figure 2 is an elevational view particularly illustrating the spring tension guide, the movement of which is shown in dotted lines.

Figure 3 is another elevational view of the invention, illustrating the adjustments of the disc supporting bracket and the tension spring guide.

Figure 4 is a perspective view of the spring tension guide detached from the device.

Figure 5 is a plan view of the presser-foot and its accompanying parts.

Figure 6 is a fragmentary view of a piece of fabric having a design of yarn or embroidery thread stitched thereon.

Figure 7 is a View taken transversely through the needle bar and spring tension guide, and

Figure 8 is a fragmentary detail View of the yielding free end of the guide.

Continuing with a more detailed description of the drawing, l designates a sewing machine head having a presser-foot bar 2 to which the 1937, Serial No. 167,251

provided with a recessed shank member 3 having a bayonet slot 4 as shown in Figure 2, which receives the conventional presser-foot set screw 5, thus rendering the device vertically adjustable on the presser-foct bar 2. At the lower end of the shank 3, an integral crescent shaped presser-foot 6 is provided having positioned across its upper side a V-shaped retainer 1 as illustrated in Figure 5.

On one side of the shank 3, and to the side of the slot 4, there is pivotally attached at a a tension spring guide 8, oblong in shape, and is retained in place by contact with the needle clamp 9 of the reciprocating needle bar [0. Integral with the lower end of the tension spring there is a V-shaped and angularly disposed guide ll, the lower point of which, together with the angle of the retainer 1 forms an aperture through which the needle l2 operates. A yarn or thread retainer I3 is provided near the upper end of the guide H and extends partially across the guide opening illustrated in Figure 3 or 4.

On the upper surface of the presser-foot ii and pivoted at the point b there is connected a bracket I l and at the upper end of the bracket Hi there is journaled for free rotation, a disc IS, the mounting being constructed with an opening it therethrough.

A hook I! is positioned on the surface of the disc l5 toward the presser-foot 6, its point being directed toward the disc periphery.

In operation, embroidery thread or yarn I8 is threaded through the opening 16, brought over the disc hook l1, thence downwardly through the guide H and its retainer l3 and through the aperture formed by the guide II and the angle of the retainer 7 which is mounted on the presserfoot 6, thus presenting the yarn or thread in position to be stitched to the fabric by the needle 12.

In order that the yarn [8 may be twisted for the sewing operation, the disc I5 is manually rotated in the desired direction, the yarn being kept taut by holding the same at the outer side of the opening l6.

, Since the tension spring contacts the needle clamp 9 in the manner previously described, the guide is moved in a reciprocating motion, as 11- lustrated in dotted lines in Figure 2, thus feeding the thread downwardly during the sewing operation.

When the presser-foot 6 is adjusted in its upper position by loosening the screw 5 and raising the shank 3, the fabric is allowed to move from side to side or in any direction, since the material is then not acted upon by the feed dogs (not shown). can be effected.

Manifestly the structure shown and described is capable of changes and modifications by those skilled in the art, and such changes which may be resorted to from time to time which may be considered within the intent of the invention may also be considered as falling within the scope and meaning of the appended claims.

What is claimed is:

1. An embroidering attachment for a sewing machine comprising in combination with the needle bar of said machine, a presser-foot for attachment to the presser-foot bar of the said sewing machine, a V-shaped retainer positioned across the said presser-ioot, reciprocating guide means actuated by the needle bar of the said machine, and means mounted on the said presserfoot for twisting and preparing the thread to be sewed for the stitching operation.

2. An attachment for sewing machines for embroidering thread or yarn to fabric, comprising in combination with the presser-foot bar and the needle bar of the said sewing machine, a

Consequently any desired design crescent shaped presser-foot for attachment to the lower end of the said presser-foot bar, a retainer positioned across the said presser-foot, and angular recess in the said retainer, resilient means attached to the upper portion of the said presser-foot to be frictionally engaged by said needle bar to be displaced thereby as the needle bar descends, guide means positioned at the lower end of the said resilient means, and means for twisting and preparing the said thread or yarn for the sewing operation.

3. In an attachment for a sewing machine, a vertically adjustable presser-foot for attachment to the lower end of the presser-foot bar of the said machine, a V-shaped retainer laterally positioned across the said presser-foot, an angular bracket pivotally mounted on the said presserr foot, a freely rotating disc mounted near the upper end of the said bracket having a central opening through which yarn is passed, means on said disc for loosely holding said yarn, and means positioned between the said presser-foot bar and the needle bar of the said machine for reciprocally feeding the said yarn into position for sewing.
